Download Datasheet

  • Description

    The NJU7042 is a tiny Rail-to-Rail Input/Output single CMOS operational amplifier The operating voltage is 2.7V to 5.5V and the input and output stage permit signal to swing between both of the supply rails. The input offset voltage is lower than 5mV, and the input bias current is as low as than 1pA, consequently very small signal around the ground level can be amplified. Furthermore, The NJU7042 is packaged with very small SOT-23-5, therefore it can be especially applied to portable applications.
